Since the introduction of ultrasound into obstetrics during the 1960s, there has been rapid progress in the detection of genetic and nongenetic defects in utero. With the development of sampling procedures like amniocentesis, chorionic villus sampling (CVS) and fetal blood sampling, the obstetrician has been able to obtain fetal tissue and the parallel improvement in laboratory techniques has allowed the diagnosis of chromosomal anomalies and single gene defects from fetal cells. Amniocentesis and CVS have become well established techniques for routine prenatal diagnosis of chromosomal and metabolic disorders and fetal tissue is now accessible throughout all three trimesters.

This statement is for the pediatrician who may be called upon to care for the child with a birth defect or genetic disorder. The involved family may wish to know and may benefit from methods that convert probability statements about recurrence risks into facts about the fetus. Many families will find knowledge and choice better than chance. Rapid advances in technology have prompted the Committee on Genetics to retire the June 1980 statement and to prepare a new one. The purpose of this revised statement is to inform the pediatrician about the current status of antenatal diagnosis as it relates to genetic and family counseling in clinical practice. The pediatrician may be called upon to help address questions about the natural history of the disorder under consideration and the possibility of intrauterine treatment. Prenatal diagnosis can give information that may improve the outcome of pregnancy and can be helpful to the obstetrician in the management of labor and delivery. The availability of prenatal diagnosis gives couples options they might not otherwise have, including termination of an affected pregnancy or preparation for the birth of an abnormal child. This enables many couples to have children, when without this information they would have chosen to be childless. The techniques currently in use or under investigation for prenatal diagnosis include (1) fetal tissue sampling: amniocentesis, chorionic villus sampling, percutaneous umbilical blood sampling, precutaneous skin biopsy, and other organ biopsies; (2) fetal visualization: ultrasound, fetoscopy, magnetic resonance imaging, and radiography; and (3) maternal serum α-fetoprotein screening.

The study presents data of different authors, as well as its own data on the frequency of multiple trisomies among the early reproductive losses in the I trimester of pregnancy and live fetuses in pregnant women at high risk of chromosomal abnormalities (CA) in I and II trimesters of gestation. The objective: determining the frequency of occurrence of double (DT) and multiple trisomies (MT) among the early reproductive losses in the I trimester of pregnancy and live fetuses in pregnant women at high risk of occurrence of HA in I and II trimesters of gestation; establishment of the most common combinations of diesel fuel and the timing of their deaths compared with single regular trisomy; comparative assessment materinskogo age with single, double and multiple trisomies. Patients and methods. During the period from 1997 to 2016, the first (primary) group of products in 1808 the concept of missed abortion (ST) of I trimester was formed from women who live in Dnepropetrovsk, Zaporozhye, Kirovograd, Cherkasy, Kherson, Mykolaiv regions. The average term of the ST was 8±3 weeks. The average age of women was 29±2 years. The second group (control) consisted of 1572 sample product concepts received during medical abortion in women (mostly residents of Krivoy Rog) in the period of 5-11 weeks of pregnancy, the average age was 32 years. The third group was made prenatally karyotyped fruits (n = 9689) pregnant women with high risk of HA of the above regions of Ukraine, directed the Centre to invasive prenatal diagnosis for individual indications: maternal age, changes in the fetus by ultrasound (characteristic malformations and echo markers HA) and high risk of HA on the results of the combined prenatal screening I and II trimesters. From 11 th to 14 th week of pregnancy, chorionic villus sampling was performed (n=1329), with the 16th week – platsentotsentez (n=2240), 18 th and 24 th week – amniocentesis (n=6120). Results. A comparative evaluation of maternal age and the prevalence anembriony among multiple trisomies. Analyzed 13,069 karyotyped embryonic and fetal I-II trimester of which have found 40 cases of multiple trisomies – 31 cases in the group in 1808 missed abortion (2.84% of total HA), 3 cases including 1 572 induced medabortov and 7 cases during 9689 prenatal research (0.51% of HA). Determined to share the double trisomies preembrionalny, fetal, early, middle and late periods of fetal development. Conclusion. There were no significant differences either in terms of destruction of single and multiple trisomies or in maternal age or in fractions anembrionalnyh pregnancies in these groups. Key words: multiple trisomies, double trisomy, missed abortion, prenatal diagnosis.

Meckel — Gruber syndrome (MGS) is a rare lethal autosomal recessive disorder characterised by occipital encephalocele, polydactyly and bilateral dysplastic cystic kidneys. A case of prenatal diagnosis of MGS at 12 weeks of gestation is described. The previous pregnancy was terminated at 20 weeks due to polycystic kidneys of the fetus. The transabdominal scan of the present pregnancy revealed occipital encephalocele of the fetus. There was no oligohydramnios, but the fetal urinary bladder was not visualised and both kidneys were enlarged. The transvaginal sonogram demonstrated intracranial space dilatation (6 mm) and encepalocele with posterior fossa cyst, protrunding from the occipital bone deffect. The kidneys had the polycystic structure suggesting cystic dysplasia and there was no evidence of the hands and feet polydactyly. Based on these findings the diagnosis of the MGS was made. Chorionic villus sampling revealed 47,XYY. The family elected to terminate pregnancy and the diagnosis was confirmed by autopsy.

Backgound <br />Invasive prenatal diagnosis (PND) through amniocentesis and chorionic villus sampling (CVS) can detect Down syndrome. Pregnant women usually experience a variety of psychological responses associated with invasive PND. This study is intended to assess depression, anxiety and stress levels and the factors related to their psychological responses in pregnant women with invasive prenatal diagnosis of Down syndrome.<br /><br />Methods <br />A cross sectional study was conducted at Kandang Kerbau Women’s and Children’s Hospital, Singapore. The psychological responses of 70 women undergoing PND were assessed by Depression Anxiety Stress Scale 21 (DASS 21) questionnaire. A multiple linear regression analysis was used to analyze association between knowledge and perceived risk with psychological responses (CI 95% and significance value p&lt;0.05).<br /><br />Results <br />More than half of the participants had normal anxiety (55.7%), stress (72.8%), depression levels (65.8%). The results revealed significantly higher level of anxiety in women with gestational age &gt;13 weeks who had pursued amniocentesis. Women with no previous children had higher levels of depression and stress. Women who pursued amniocentesis had significantly higher anxiety scores compared to women undergoing CVS (p=0.015).<br /><br />Conclusions <br />Women’s psychological responses are associated with gestational age, type of procedure and parity. The level of anxiety increased in women who underwent amniocentesis for diagnosis of Down syndrome. Knowledge and perceived risk of having a baby with Down syndrome do not seem to have psychological effects to women.

ABSTRACT In the Microcitemico Hospital the first prenatal diagnosis in Europe of beta-thalassemia was performed in 1977 using fetal blood sampling and globin chain analysis at 20th week of gestation. Since then, more than 55,000 prenatal invasive procedures were performed in our center for several genetic and chromosomal diseases. In 2011, our department has been introduced as a center for teaching invasive diagnostic procedures under the umbrella of the Ian Donald International University School of Medical Ultrasound. After a period of tutoring for 2 or more weeks, fellow doctors who intend to learn invasive techniques for prenatal diagnosis under the direct supervision of a senior tutor (G. Monni) can receive the basic diploma in invasive prenatal procedures (Fig. 1). In the following study, we describe the training process of the invasive prenatal procedure performed by transabdominal chorionic villus sampling (TA-CVS).
